Using gG fuses, type 1 coordination will be achieved. To achieve type 2 coordination, semiconductor fuses must be used.

Suitable switch fuse for the recommended gG fuses or semiconductor fuses.

The line contactor is not required for the softstarter itself but often used to open if OL trips

Overload protection is always required to protect the motor

Using by-pass will reduce the power loss and allow more starts per hour
